Method using inarching to rejuvenate ancient tree

Abstract

The invention discloses a method using inarching to rejuvenate an ancient tree and belongs to the technical field of ancient tree rejuvenation. The method includes the steps of firstly, selecting a robust tree coordinal with a to-be-rejuvenated ancient tree to serve as the stock; secondly, cutting off branches at the lower end of the stock to keep the trunk of the stock, and removing diseased andwithered branches on the stock; thirdly, processing the ancient tree, to be more specific, selecting the well-developed branch of the ancient tree to serve as the scion, and peeling the lower-end inarching position of the scion to expose the xylem; fourthly, processing tree roots; fifthly, inarching; sixthly, moisturizing; seventhly, covering soil; eighthly, performing later maintenance; ninthly,pruning. The method has the advantages that ancient tree rejuvenation is performed by means of root inarching, the ancient tree seedling can directly and conveniently absorb nutrition, inarching survival rate is increased, inarching time is shortened, the root part after the inarching is located below the soil, all the overground part is the ancient tree, and the attractiveness of the ancient treeis increased.

Description

technical field [0001] The invention relates to the technical field of old tree rejuvenation, in particular to a method for rejuvenating old trees by abutting.

Problems solved by technology

The existing bridging method is generally carried out at 10-15cm above the root system of the ancient tree. After the connection, the branches of the ancient tree absorb nutrients slowly, the survival rate is low, and the old tree after rejuvenation is different from top to bottom, which affects the overall appearance.
